Question

According to a certain country’s department of education, 40.0% of 3-year-olds are enrolled in day care.

Answer 1

Given parameters:

Percentage of enrollment of 3-year-olds = 40%

Unknown:

Probability that a randomly selected 3-year-old is enrolled in a day care = ?

Probability is the likelihood of an event to occur.

   Probability  = $\frac{Possible outcome}{Total out come}$

In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.

  We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.

The possible enrollment is 40 and the total is 100;

Input the parameters and solve;

      Probability  = $\frac{40}{100}$   = $\frac{2}{5}$

The probability that any randomly selected 3 year old is enrolled in day care is $\frac{2}{5}$
